LIQUm-FEEDING DEVICE.

Specification of Letters Patent.

Patented Mar. 27, far a.

Application filed April 16, 1915. Serial 1W0. 21,700.

To all whom it may concern:

Be it known that I, LOUIS 1E. BALTZLEY, a citizen of the United States,residing at VVeehaWken, in the county of Hudson and State of New Jersey,

Feeding Devices, of which the following is a specification.

This invention relates to liquid feeding devices and comprises acontainer having fluid delivering means at one end, a valve forregulating the size of the opening in said delivering means, a threadedstem carrying the valve and leading to the upper portion of thecontainer, a spring supportwhich the stem is threaded, and a handle foroperating the same to lower and raise the valve.

This feeding device is particularly useful as an oil dropper to be usedfor olive oil and the like in preparing salad dressings. It is providedwith tubular delivering means adapted to fit a hole in the top of aculinary beater and to be maintained in tubular delivering means wherebythe operator may have both hands free, one to operate the handle of thevalve stem and the other to operate the handle of the beater. Inpreparing mayonnaise dressing the best results are obtained when,particularly at the beginning of the operation, the oil is fed to thesubstance that is to be mixed in very small amounts. The oil should befed drop by drop and should be thoroughly mixed with the other substancein the beater.

fter thorough mixing of these small quantities of oil and othersubstance the oil may vention serves admirably to feed the oil asrequired.

The invention has for its objects the provision of an oil feeding devicecapable of h have invented certain new and useful Improvements inLiquldplace by such deviceof a size adapted to fit a hole in the top ofa culinary beater. The upper edge of the container is, provided with aflange or car and a removable resilient stem-supportlng member. Thismember preferably has openlngs near opposite ends, the outer edges ofthe openings serving to engage the body of the container under the ears.

11 the accompanying drawings Figure 1 is a side elevation of the liquidfeeding device. Fig. 2 is a vertical section showing the rodand valve inelevation. Fig. 3 is a top plan view. Fig. 4 is a perspective of thespring supporting member. Fig. 5 is a section of Fig. 4 along line 5-5,and Fig. 6 is a modification of the lower end of the device.

Referring to the drawings, reference numeral 1 indicates the funnelshaped container' having the flange 2 and theears 3 projectingtherefrom. The top of the container is normally open- At the bottom itis provided with the fluid delivering throat 4. This may be brass orsteel riveted to the body as is shown at 5. If desired however thethroat may be a continuation of the body of the container as is shown inFig. 6. The body ofthe container is preferably made of aluminum or otherlight metal. This throat should advantageously be made of a hard metal,as soft metal would soon be bent out of shape.

In itsarch the Valve 6 normally seats in the end of the threat 4. It isa cone valve which is ar ranged to gradually enlarge the cross sectionalflow area of the throat when the valve is pressed downwardly. The valveis supported in place by a stem or red 7 screw threaded at this upperend 8 and pasing through the resilient supporting member 9. This memberis made of light spring arch shaped metal. It is provided at eitherextremity with an opening 10 having edges 11. edges are about the samedistance apart as the width or diameter of the container at this upperportion. Downward pressure upolithe middle of this arched spring memberwill of course spread the edges 11 apart. To place the spring member inposition the edges 11 are spread apart by downward presure upon themiddle of the spring member and the holes 11, which are larger than theears 3 of the container are placed over such ears. When released frompressure the inherent resiliency of this member causes it to assume itsarched form and the edges 11 are therefore brought into contact with thebody of the container under the ars. In order to provide for adjustmentof the screw rod in this spring member I split it as is shown at 12. Oneedge 13 is elevated slightly above the edge 14 a distance correspondingto one thread on the rod. The rod is provided with a rigidly fastenedknurled thumb nut or handle 15. The operation is obvious from theforegoing.

What I claim is:

A liquid delivering device comprising a container having at its upperend means for holding a rod supporting member, liquid delivering meanssaid delivering means, -a threaded rod attached to said valve, a movablearch-shaped resilient rod-supporting member bridging the top of thecontainer and engaging the said holding means at the upper end andhaving a threaded opening through which the rod extends, and a handle onsaid rod.

In testimony whereof, I aflix my signature.
